Caffeinated Interfaces Enhance Alkaline Hydrogen Electrocatalysis

Hydrogen electrocatalysis: a basic solution.

Electrocatalysis for the Hydrogen Economy

This chapter deals with the concept of “hydrogen economy”, which was introduced by John O.M’ Bockris in 1972. We summarize the fundamental principles and the progress for the reactions relevant to the hydrogen economy, namely the hydrogen and oxygen evolution for water electrolyzers, and the hydrogen oxidation and oxygen reduction for fuel cells. The activity of each reaction can be correlated ...

Alkaline Methanol Fuel Cell Electrocatalysis Using a Pressurized Electrochemical Cell

Layer-dependent electrocatalysis of MoS2 for hydrogen evolution.

The quantitative correlation of the catalytic activity with the microscopic structure of heterogeneous catalysts is a major challenge for the field of catalysis science. It requests synergistic capabilities to tailor the structure with atomic scale precision and to control the catalytic reaction to proceed through well-defined pathways. Here we leverage on the controlled growth of MoS2 atomical...

Highly branched cobalt phosphide nanostructures for hydrogen-evolution electrocatalysis

CoP nanostructures that exposed predominantly (111) crystal facets were synthesized and evaluated for performance as electrocatalysts for the hydrogen-evolution reaction (HER). The branched CoP nanostructures were synthesized by reacting cobalt(II) acetylacetonate with trioctylphosphine in the presence of trioctylphosphine oxide. Electrodes comprised of the branched CoP nanostructures deposited...
